A database that was originally from SQL Server 2008, was restored into SQL Server 2012. A backup from SQL Server 2012 was made and I am trying to restore it on my local SQL Server 2008 Express. However I get an error ‘Specified cast is not valid’ (SQLManagerUI).
I have generated an SQL Script from 2012 and set it so that it will generate with compatibility to SQL Server 2008. However it is a large sql file, around 700mb.
I recall before that I had tried to run a script of that size before on my local SQLExpress and also got an error.
Is there a way I can get a “large” database from SQL Server 2012 into SQL Server 2008 Express?
Thanks to Marc and Aaron for providing the answers.
The quick answer is no, it’s not possible to restore a backup file from a higher version to a lower version of SQL Server.
A work around would be to generate the scripts to create the database.
You can target the script generation to a lower version.
Please see comments above for more information.
